This is true. However, *responsible* breeders are working very hard to change this. Not only are responsible breeders breeding away from health problems, but they are active in their breed clubs and collectively donate thousans, even millions of dollars to help fund research to make ALL dogs healthier. Our breed club (the DPCA) is reknowned for making health a priority, and supporting research that is trying to make all dogs healthier.
How can a litter whose pedigree has never been health-tested be assumed to be healthy?
If the OP had done full health testing, I wouldn't have an issue with it. But as it stands, the parents of this litter have no health testing. And that truly is sad.
